Hair Follicle Drug Testing - Winchester, NH

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by capturing biomarkers within the growing hair fibers. When gathered close to the scalp, hair can provide a detection window of up to approximately three months for alcohol and other substances. Hair is straightforward to collect, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch segment of around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not present, a similar quantity of body hair can be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is entered into a laboratory's system. This step involves confirming that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not included in an electronic chain of custody protocol.

Screening involves a preliminary evaluation for drug presence. Although Screening is an economical approach to discount drug presence in most samples, a positive result requires confirmation to be accepted in legal proceedings. Any samples with a presumptive positive result in Screening need a subsequent confirmation.

If a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. In this step, drugs are extracted from hair in much lower concentrations than with other methods (such as urine or oral fluid), making hair drug screening one of the most complex methodologies.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are cleansed before confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can recognize drug use for up to 90 days, while urine tests have a shorter detection window.
• Difficulty to cheat: It is quite challenging to falsify a hair drug test, resulting in more precise outcomes.
• Provides historical data: It demonstrates a pattern of drug use over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: It typically takes 5-7 days for drugs to be observable in hair.
• Cost: Hair drug tests are usually more costly compared to other drug testing techniques.
• Variations in results: Elements such as hair color and personal differences in hair growth can impact the concentration of drug metabolites.

Note: Although often termed "hair follicle tests", the actual test examines the hair strand and not the hair follicle beneath the scalp
